作者曾观察到晚餐后胃内pH先下降至低值,半夜时又上升。为证实提早进晚餐能否加强此种效应,对23名健康志愿者(12名男性,平均24岁)进行了试验。方法:检查日自中午开始禁食,下牛4时入院留观15小时。经鼻插入pH电极(粗4mm),透视下定位于胃体部,外接记录器。下午5时开始测定并记录。用标准化膳食。患者在实验室随机分为下午6时及9时两组进晚餐。11时上床,次晨6.45时起床,7时进早餐,8时离院进行正常活动,12时午餐。三餐外不进其他食物、药物,禁烟酒。下午4时回院,透视复查电极位置后取出pH电极。22小时间持续记录结果,用电子计算机进行分祈。
The authors have observed that the pH of the stomach first drops to a low value after dinner and rises again in the middle of the night. To confirm whether such an effect could be enhanced by early dinner, 23 healthy volunteers (12 men, average 24 years) were tested. Method: Fasting began on the day of the examination and was admitted to the hospital at 4 o’clock for 15 hours. Nasal pH electrode (4mm thick), located in the corpus perspective, external recorder. Measurements taken at 5 pm and recorded. Use a standardized meal. Patients in the laboratory were randomly divided into 6 pm and 9 pm two groups into the dinner. Go to bed at 11 o’clock, get up the next morning at 6.45, breakfast at 7 o’clock, leaving the hospital at 8 o’clock for normal activities, lunch at 12 o’clock. Do not eat other meals, drugs, no alcohol and tobacco. 4:00 back to the hospital, after reviewing the location of the electrode and remove the pH electrode. 22 hours continuous record of results, using computer to pray.
